Tomlinson, who entered the game against the Bills with 1,146 yards, surpassed 1,200 with a 51-yard touchdown run with 66 seconds left in the first quarter. Dickerson set the standard from 1983-89 with the Los Angeles Rams and Indianapolis.

The touchdown, which put the Chargers up 10-0 on Buffalo, was Tomlinson's 25th of the year, inching him within three of matching the single-season record set by the Seattle Seahawks' Shaun Alexander last season.

Tomlinson has scored a TD in 10 of San Diego's 12 games this season and has scored 17 times in his past six games. His 27 scores, including two passing, account for more than half of the Chargers' 44 this season.
